• Foundation of Ergosign in 1998
Decades of experience as an active sport shooter, the development and fabrication of
ergonomic grips for pistols and revolvers and of many accessories as well as the involved
mechanical understanding for production processes and their transformation with CAD/
CAM and CNC technologies are the basis for the realization of innovative products.
Many well-known manufacturers of firearms (like Heckler & Koch, Hämmerli, Walther,
Sig Sauer) were able to successfully realize numerous projects in direct cooperation
with Wilfried Nill.

– a story of success
– Advantages of the modular
stock system
Owing to his personal enthusiasm for clay target shooting, Wilfried Nill set himself the
goal of designing an ergonomically perfect fitting shotgun stock in 2005 yet. The result
of this experience and development is presented to you in detail on the following pages.
National and international top shooters have very quickly recognized the advantages of
the modular stocks and are convinced by the improved control of the shotguns provided
by ergonomic optimization and individual possibilities of adjustment. On pages 15 and
16 we are presenting you a short list of references.
The worldwide success since the introduction of the Ergosign EvoComp stock system
in summer 2009 is speaking for itself. The current peak of EvoComp during the Olympic
Games 2012 in London with four medals could set lasting trends (see below).
With the Ergosign EvoComp, Wilfried Nill is continuing the estimated family tradition in
order to support our customers by offering them the optimal connection between man
and sporting tool.
Ergonomic grips in different sizes for left and right handed shooters
One significant advantage compared to conventional stocks lies in the anatomical
moulding of the pistol grip, which gives the stock an absolutely unique, comfortable and
secure hold. Due to its optimal ergonomic design, the position of the trigger finger (with
respect to the trigger) remains constant, thus reducing the recoil effects tremendously.
Individual adjustability to body/anatomy and shooting position
A basic requirement for a steady mount position and therefore successful shooting
is a personalized adjustment of the stock depending on the shooter’s anatomy and
shooting stance. These preferences change with time and can be corrected with ease
by resetting the stock.
Modular construction allows the interchangeability of all components
All stock parts can be tuned to different requirements if changes occur. If you are going
to switch guns, you will only need to purchase a new grip (and maybe a different comb,
if using a different rib height) which your authorized dealer will gladly install for you.
The gross weight is only 850 grams [30 oz.] for the standard version.
All settings are reproducible via scales on the system.

– the basis for success
Ergonomic grips with beavertail,
small thumb rest and slight
palm swell
With finger grooves and Rhomlas®-surface
structure in four different sizes (XL, L, M
and S) or without finger grooves in the
sizes L and S, with stippled surface as
an individual custom-made fabrication
according to a hand outline sketch or after
a personal orthopaedic adjustment: all our
grips are produced for personal fitting to all
different kinds of possible hand shapes.
Drop of the butt plate
Depending on the length of the shooter’s
neck and the mounting position, the
level of the butt plate can be individually
adjusted within a range of approx. 40 mm
[1.575 in] to approx. 60 mm [2.285 in] (for
a middle section 4°). By mounting a higher
clamping collar between the comb and the
middle section (see page 10) the height of
the butt plate rises proportionally.
Please find our detailed description
on page 12.
Pitch adjustment
Cast
The pitch is fully adjustable by approx.
90°- 82°. Once it has been fitted correctly,
the gun will remain in exactly the same
position after a shot. This greatly increases the hit ratio on the second shot of the
target pair.
For up to 9 mm by adjusting the butt
plate. Additionally the butt plate is rotatable by ± 10°.
Pitch adjusting plate +4°
An extended pitch adjustment of +4° is
optional. For shooters with an upright
shooting position and a big chest measurement the pitch can be additionally
extended by 4° (can be recommended for
a heightened middle section under 0° and
for the TR version).
4
Cast + 4 mm
For shooters with a short neck or a big
chest measurement the additional cast
of about 7-13 mm (standard 3-9 mm)
optimizes the adjustment to the body –
to reach a higher comfort.
®
– the basis for success
Comb
Stock length
The correct position of the head to the rib is essential for a precise point of impact.
For this reason, the standard comb of 33 mm can be fully adjusted in height (drop)
from approx. 42/46 to 36/36 (with a comb of 38 mm from approx. 37/41 to 28/28) and
approx. 4 mm in width (cast +1 to +5 mm).
Having a range of adjustment from approx. 340 mm to approx. 390 mm, it is simple to
fit the stock with the telescopic tube to the individual body size. Additionally, a shorter
version for smaller shooters or for shooters with short arms of approx. 320 to 360 mm as
well as a long version for very tall shooters with an adjustment range of approx. 360 to
430 mm are available.

Which stock configuration is the ideal one for me?
1. Which of the following anatomic
conditions do apply for me?
a) An average neck
and shoulder anatomy
b) A long neck with
a low gun position
c) A long neck with
a high gun position
d) A short neck with
a low gun position
e) A short neck with
a high gun position
2. Which posture is usually
the best for me?
It also depends from the preferred stock
length and posture whether 3.a) or 3.b) is
recommendable for the shooter.
4. Higher ribs
a) 10/15mm higher: possible for all disciplines and favorable for shooters of
categories 1.a) -d) and 2.b).
b) 20/25 mm higher: recommendable for
all trap, double trap and DTL shooters,
especially for 1.b) and 2.c).
3. What is the position to place
the shotgun at my shoulder?
On the basis of all the factors listed under
points 1-4, the drop of the butt plate in
relation to the top edge of the rib will result.
Within the different stock configurations,
the shooter can use the adjusting range
of the drop of the butt plate (see picture:
height/drop of butt plate on page 4). The
smaller the drop between the top edge
of the butt plate and the principal axis of
b) Above the collarbone on the muscle
at your shoulder: less drop of the butt
plate ► less upcoil at the muzzle
rib and also depends from the distance
between eye and cheek-bone and from
the requested upshot.
Meanwhile, most gun manufacturers also
produce shotguns with heightened ribs,
which help to offer you a more relaxed
shooting position and a reduced upper
recoil after the shot, depending on the
anatomic conditions.
a) Body and head slightly leaning
forward (recommended)
b) A body leaning forward keeping
the head a little further to the front
c) A body standing upright keeping
the head almost vertical
a) Below the collarbone: more drop of
the butt plate is necessary ► more
upcoil at the muzzle
the barrels is, the less is the upper recoil
of the shotgun with a correctly adjusted
pitch. The drop of the comb always refers
to the position of the upper edge of the
c) 30/35 mm higher: for trap, double trap
and DTL shooters from the categories
1.b) and 2.c)
5. Example for the following case:
An average neck and shoulder
anatomy, body and head slightly
leaning forward, weight on the left leg
approx. 55 %, on the right leg approx.
45 % (right hand shooter). In this case,
the standard version offers the best
requirements for an individual stock
adjustment to the shooter’s conditions.

Summary:
When ordering a shotgun or a new stock
system, the shooter should seek analysis
and advice from a professional shooting
instructor or gun fitter with own shooting
experience, who is knowledgeable
on innovative shotguns/stocks. The
completed questionnaire is one of the
most important factors (see page 14).
Moreover, photos from different perspectives – with your shotgun in shooting

to find the best fitting stock configuration.
Not only the balance of your shotgun but
also your anatomy and preferred shooting
position are of great importance for the
configuration of your stock system. Most
shooters prefer the posture from our first
example. We keep the most popular and
common shotguns available and will be
pleased to help you with our advice.

The standard version of our stocks comprises the
following configuration:
• Grip with finger grooves, Rhomlas® surface structure in
the sizes XL/L/M/S for right hand or left hand shooters
• Stock length adjustment of approx. 340-390 mm
• Drop of butt plate approx. 40-60 mm middle section 4°
• Adjustable comb R33 (36/36 – 42/46 mm) for skeet/sporting
• Alternatively comb R38 (28/28 – 37/41 mm) for trap or
for a very small distance between cheek-bone and eye
• Fully adjustable stock ending with a butt plate made of
walnut wood and a partial rubber pad, alternatively with
a butt plate made of elastomere (for trap or sporting)
• Grip and comb made of walnut
• Aluminium parts with black coloured or titanium

Skeleton version
Compared to the standard version the middle section of
the stock is skeletal. This provides the stock with an even
more technical appearance and reduces its weight by
approx. 15 grams. The skeleton version is available for a
stock length of 340-390 mm and 360-430 mm.

Shortened version of 20 mm
For smaller shooters or for shooters with short arms
a shortened version is additionally available with an
adjustment range of 320 to approx. 360 mm in length.
This version can only be delivered with aluminium parts
in black colour (not in skeleton). Moreover, the combs
are 20 mm shorter.

20 mm extended version
For tall shooters or shooters with long arms we can offer
an extended version with an adjusting range of 370 to
approx. 450 mm length. This version is only available
with black aluminium parts (in skeleton) and can be
supplied as an option for all stock configurations.

Clamping collar +10 mm for heightened ribs of approx. 10-15 mm
Clamping collar +30 mm for heightened ribs of approx. 30-35 mm
By mounting a heightened clamping collar of approx. 10 mm between the middle section
and the comb the drop of the comb can be adapted to the heightened rib (e.g. Perazzi
MX2000/3, MX10, Beretta X-Trap, Caesar Guerini etc.).
See left descriptions, clamping collar however 30 mm higher.
Clamping collar +20 mm for heightened ribs of approx. 20-25 mm
Version TR 1°
Our clamping collars offer the best possible flexibility in adjustment for shotguns which
need a modified drop (even after the additional mounting of heightened ribs). Further
differences in height can be balanced through the possibility of choosing heightened
combs with its range of adjustment.
This version is particularly recommendable for shooters who have a short neck and a
high gun position. The drop is adjustable from approx. 35-55 mm. The comb has been
drawn for approx. 5 mm forwards, the drop is parallel to the rib at the front/at the back.
Pitch 93° to 85° (Special version +4° is adjustable from approx. 93° to 81°).

Version TR +10 1°
Special version Perazzi MX2008 +30 0°
In comparison to the previous system (TR 1°) the drop of the butt plate is adjusted by
approx. 10 mm in height. This configuration can be used as a base for the MX2000/3
(and other shotguns with a heightened rib of 10-15 mm) in connection with a +10 mm
clamping collar for a 20-25 mm heightened rib or with a +20 mm clamping collar for a
30-55 mm heightened rib.
See bottom left description, but adapted to the MX2008.

Recoil reducer
Special version Perazzi MX2005 + 20 0°
On the request of various double trap top shooters, we have developed further stock
configurations with removable trigger group for the Perazzi production series. In this
special version the complete back stock part is raised to the level of the barrel rib on
MX2005, so that the drop is correspondingly adjusted. The result is that the recoil of
the shotgun is straighter to the shoulder and that the muzzle jump is considerably more
influenced by the pitch adjustment (in comparison to stocks in standard version).
Resulting from many years of development and numerous tests a hydraulic
system dampens the back stock through
a cylinder against the shooting direction.
By an adjusting screw the damping can be
regulated according to munitions, barrel
length and choke drillings as well as the
body measurements which influence
the recoil. Thus the shooter will get the
requested feedback.

Rhomlas®-surface structure
12
Ergonomic grip without
finger grooves
Another high point of the development
is the integration of Rhomlas® surface
structure which is well-proven for many
years and is appreciated by international
top shooters. With much attention to
detail, non-slip segments are incorporated at crucial points in a complex process.
A dynamic design – but “Ergosign” is also
created for practical use.
The version without finger grooves is
exactly the right choice, if the shotgun is
used by multiple shooters (for example
as a training-, rental- or club gun) or if a
plain moulding is preferred. This grip is
available with Rhomlas® surface in the
sizes L and S.
Individual grips – fabricated according to your hand outline sketch
Orthopaedic grip customized
according to a plastic moulding
Shooters whose hands highly differ from
the standard measurement (for instance
very short/thick or very long/slim hands)
have the possibility to order individual
grips fabricated according to an exact
hand outline sketch for an additional fee.
Thus the shooter gets individually fabricated grips with stippled surface in the
palm area which are specially adjusted to
his shooting hand.
During a personal fitting appointment
an exact wood/plastic moulding is made
from the shooter’s hand by using a grip
blank. All the contour elements of the
grip are adjusted in detail to the shooter’s
hand and his shooting position. The
result is a grip which fits “like a glove” and
which always guarantees the same hand
position on the stock. Thus the exact
consistent position and steady distance to
the trigger can be guaranteed.

For shotguns with heightened ribs our different combs and
clamping collars (the holder between middle section and
comb) allow one to raise the standard ratio of the drop in
proportion to the rib. For widely varying head positions we
offer the possibility of lengthening the comb. Combs are
available with a height of 33, 38, 43 and 48 mm, the corresponding clamping collars are available with a height of +10,
+20 and +30 mm. For combs R33 the height adjustment
pins are 14/17 mm high (for R38 17/20 mm). Additionally
height adjustment pins of 23 mm are available.
The balancer offers the possibility to balance the weight
of the shotgun (approx. 68 to 240 grams). The longer the
size of the barrel, the more weight is needed on the stock.

have made the right choice. Our results have increased and are more stable now, thanks
to comfortable position of our hands and exactly adjusted stocks. We have made the
right choice. Thanks for collaboration with Nill company.”
(Vitaly Fokeev, top shooter and Kirill Fokeev´s Dad)
“We put the Ergosign stock on her gun in mid February 2015 and we saw an improvement
in her score right away, her average went from a 17 to a 20 within one week after installing.
The EvoComp is the perfect stock for youth shooting athletes, because it can be adjusted
as the athlete grows and that adjustment may be needed 3 to 4 times a year depending on
how fast they grow. This has proven to have been a great investment for us!“
